The Repentance Tower is a very rare example of a mid-16th century watch tower standing on Trailtrow Hill. Built in 1565 by John Maxwell, the tower takes its name from an inscription Repentance carved on the stonework above the entrance door.
The watch tower remained with the Maxwells until in around 1627 the sixth Lord Herries sold Hoddam Castle and the tower to Sir Richard Murray of Cockpool (Comlongan) Castle. The barony and castle were purchased in 1690 by John Sharpe and remained with that family until 1878.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
